– I create group in the front office => OK
– I activate groupblog in my group with default parameter (new blog) => OK
– On group page, I have “Blog” tab, I clic, I am on the group blog => OK (http://g.wordpress.webcaviste.definima.net/groupes/vefzvf/blog/)
– On group blog, I have the first defoult post, and I have “About” button (see previous link, it’s in french : “A propos” = “About”)
– If I clic on “About”, I have this link adress : http://g.wordpress.webcaviste.definima.net/vefzvf/blog/. The same as before without my group slug (“groupes”)
– And then, I have a horrible page without CSS
– Moreover, I can’t find “create post” link or whatever looks like the blog admin in the front end.

I think my problem is about the plugin config, but I think I’ve tested all possibilities… Am I missing something ?

Hi guigoz….pages should link to that url, since you are viewing a blog page…not a group page. So the url is correct, however your pagelayout should be identical as the BuddyPress theme. Not sure why you are having trouble with this.
